The LMS algorithm is usually adopted to adjust weight coefficients of the adaptive transversal filter whose output is an estimation of the echo signal.
通常采用LMS算法对自适应横向滤波器的加权系数进行调节。
This paper proposes a novel decision feedback equalizer (DFE) algorithm based on a sliding window generalized multichannel fast transversal filter (SWFTF).
本文提出了一种基于滑动窗广义多路快速横向滤波(SWFTF)的自适应判决反馈均衡器(DFE)算法。
The equalization in frequency domain is the feed-forward filtering of the DFE. And the traditional transversal filter is used in the feed-back filtering in time domain.
The coefficients of the FIR transversal filter was identified by using adaptive RLS algorithm while the output signal of the vibration pick-up was input into the FIR transversal filter.
The correlation algorithm in training period and the LMS algorithm in run period can be combined in the identical transversal filter structure, so that it speeds up the channel estimator convergence.
